First INA
Japan and Southeast Asia were major refuges for Indian nationalists living in exile before the start of World War II. Japan had sent intelligence missions, notably under Major Iwaichi Fujiwara, into South Asia even before the start of the war to garner support from the Malayan Sultans, overseas Chinese, the Burmese resistance and the Indian movement. These missions were successful establishing contacts with Indian nationalists in exile in Thailand and Malaya, supporting the establishment and organisation of the Indian Independence League.
At the outbreak of World War II in South East Asia, 70,000 Indian troops were stationed in Malaya. After the start of the war, Japan's spectacular Malayan Campaign had brought under her control considerable numbers of Indian prisoners of war, nearly 55,000 after the Fall of Singapore alone. The conditions of service within the British Indian Army as well as the conditions in Malaya had fed dissension among these troops. From these troops, the First Indian National Army was formed under Mohan Singh and received considerable Japanese aid and support.
